"The fuss about global warming is grossly exaggerated,"
writes Dyson in his new book Many Colored Glass: Reflections on
the Place of Life in the Universe, published Wednesday.

He pours scorn on "the holy brotherhood of climate model experts
and the crowd of deluded citizens who believe the numbers predicted by
the computer models".

"I have studied the climate models and I know what they can do.
The models solve the equations of fluid dynamics, and they do a very
good job of describing the fluid motions of the atmosphere and the
oceans. They do a very poor job of describing the clouds, the dust, the
chemistry, and the biology of fields and farms and forests," writes
Dyson.

"Many of the basic processes of planetary ecology are poorly
understood. They must be better understood before we can reach an
accurate diagnosis of the present condition of our planet," he
says.
